Anyone have one? Montane/ others? What are they like for breathability compared to Gore Tex and Event?

Have an Endura entrant jacket – good bit of kit, light, waterproof and reasonably breathable. It’s probably the best jCket i’ve tried in terms of managing moisture during aerobic activity. I do have a goretex Pro-shell jacket that works well for climbing and so on, but I’ve not used it on the bike.

Worst of the lot was a Paramo Velez Adventure Light, too heavy and thick for mountain biking, although it would be okay for the depths of winter.
